摘要： PURPOSE:To improve the data transfer capacity of a whole system by providing each node with a function to receive data from one highway in principle and transmit and receive the data to/from all the highways only in the case for a common data area. CONSTITUTION:A network system consists of a trunk line node 300, a trunk line LAN 301, a branch line LAN 303, and terminal equipment 304. Then, each node device 300 on a loop network executes reception processing operation for a communication frame inputted from one specified communication channel among plural communication channels (highway) multiplexed physically or logically, and executes transmission processing operation by using the communication frame flowing in the optional communication channel selected correspondingly to a destination node. Thus, the data transfer capacity of the whole system can be improved without accelerating information processing speed at each node device 300.

摘要： PURPOSE:To improve both working efficiency and maintenance performance with a loop-shaped network by replacing a faulty area without affecting the transmission system of a loop-back state in case >=2 faults occur at a time in different transmission systems. CONSTITUTION:A repeater part 131 consists of a transmission part 141 led to a transmission line 101 of operation system and a reception part 151 led from a transmission line 102 of spare system. While another repeater part 132 consists of a reception part 152 for the line 101 and a transmission part 142 for the line 102. In case >=2 faults occur at a time in two different transmission systems, the parts 134 and 137 including the faulty areas can be replaced with others since they form no loop-back state.

摘要： PURPOSE:To reduce the number of signal lines between a data terminal and a data switching network by synthesizing plural pairs of signal lines and then separating these signal lines again in the interface between the data terminal and data switching network. CONSTITUTION:A transmission data line T and a control line C from a terminal 1 having an X.21 interface are combined to a T' line in an interface device 3, then separated into respective information of the T line and C line of the X.21 interface again by an interface device 4 in a network terminating device 2. On the other hand, a receiving data line R to the terminal 1, an indication line I and a signal element clock line S are synthesized to an R' line by the device 4 in the device 2, separated again in the device 3 and then transmitted to the terminal 1. Therefore, the devices 3 and 2 are satisfactorily connected only by connecting the two pairs of signals lines T', R', and if the device 3 and the terminal 1 are arranged adjacently, the section connecting the five pairs of signal lines T, R, C, I and S requires no long distance.

摘要： PURPOSE:To prevent disabled communication by detecting the erroneous occupancy of a packet region depending on the relation between the continuous passing number of time of an occupied packed region passing through the own node and the number of nodes connected in a loop network, to release the region. CONSTITUTION:A detecting circuit 31 supervises always whether a packet region of a frame passing through a node device is in operation or idle, every time the packet in operation passes, a signal (a) is applied to a counter 32 so as to increment it. When an dile packet is incoming, a signal (b) is applied to the counter 32 so as to reset it. When a comparator circuit 33 recognizes that the value of the counter exceeds the node number connected to a loop, the circuit 33 discriminates that the information of ''in operation/idle'' is rewritten because of an error like a fault, s signal is given to a clear circuit of packet region operating information, the information is rewritten into packet region ''idle'' and the packet region is restored to give a packet operating right to a node at the downstream.

摘要： PURPOSE:To multiplex a control signal on a data signal by providing an interface converting circuit comprising a multiplexer circuit, a demultiplexer circuit, a synhronizing circuit and a digital PLL circuit to each of a data exchange network and a data terminal device respectively to reduce the number of signal lines. CONSTITUTION:A data transmission system is constituted of a terminal device DTE and a line terminator DCE, and the multiplexer circuit 2 of the interface converting circuit (2) of the DCE multiplexes the information of R and I lines of an X.21 interface. Further, the multiplexer circuit 1 of the interface converting circuit (1) of the DTE multiplexes the information on T and C lines in the interface and transmits it to a line T'. Then the conversion and transmission of the information are controlled by respective synchronizing circuits 1, 2, the number of signal lines is reduced and the control signal is multiplexed on the data signal.

摘要： PURPOSE:To facilitate an easy dialing operation by using a KANA (Japanese syllabary) input means as a telephone number selecting means. CONSTITUTION:When a character key in a pad 16 is pushed, a corresponding position signal is sent to an abbreviated dialing controller 14. The controller 14 stores the value of the position signal after converting it into a corresponding character code and at the same time supplies it to a display device 18. This operation is repeated by a frequency equivalent to the number of characters of an abbreviation for selection of telephone number. Then the controller 14 detects the coincidence among the character code trains, the abbreviations stored in an abbreviated dial memory 19 and the abbreviations in a correspondence table of telephone numbers and displays the digit train of the corresponding telephone number to a display device 18. At the same time, a circuit switching signal is transmitted to a switching circuit 11 and then an automatic dialing circuit 20 is controlled to transmit the dial signal corresponding to the telephone number.

摘要： PURPOSE:To facilitate an easy reply to an inquiry as well as an easy rearrangement of the reply, by coding the contents of the reply to the inquiry and at the same time delivering the replying state in a list to the inquirer. CONSTITUTION:A message is edited through an off-line operation, and the telephone number of a mailing device is dialed after picking up a telephone receiver. Otherwise a call key TM is pushed among function keys 11 after picking up the telephone receiver. When a circuit is connected to the mailing device, the mailing device transmits a signal to permit the transmission of the message. When a telephone bell rings and the telephone receiver is picked up, the voices of a remote subscriber are heard in a normal calling case. However a special tone is given in the case of an electronic mail incoming. With a push of a TXT key, the header characters of a received mail are displayed on a screen. At the same time, a hard copy is delivered to a printer. The contents of the body of a message are also delivered after the header sentence in the case of a normal mail. For a registered mail, a confidential mail, and a confidential registered mail, a guidance sentence is displayed on a guide column to request an input of an ID card when the output of the header sentence is over.

摘要： PURPOSE:To decrease the load of a processor, by providing a counter counting the change in a line signal in a subscriber circuit and counting the change in the signal with the hardware. CONSTITUTION:A line signal LS is inputted to an FF6 and the output of the FF6 is inputted to an FF7. Logical gates 11, 12 detect that the values of the FFs 6, 7 are the same and an FF8 is operative accordingly. For example, suppose that the period of a clock signal CK is 2ms, when the signal LS within 2ms is changed, the content of the FFs 6, 7 is not the same and no signal is outputted from the gates 11, 12. Thus, even if a short pulse due to the chattering enters the signal LS, it is eliminated. Then, the number of dial pulses is counted by inputting an output of the FF8 to a counter 9. On the other hand, a processor 1 fetches the content of the FF8 and counters 9-1-9-4 by transmitting a specific address to an address bus 2.
摘要翻译：目的：降低处理器的负载，通过提供一个计数器来计数用户电路中的一条线路信号的变化，并用硬件对信号的变化进行计数。构成：将线信号LS输入到FF6，将FF6的输出输入到FF7。逻辑门11,12检测到FF6,7的值相同并且相应地操作FF8。例如，假设时钟信号CK的周期为2ms，当2ms内的信号LS改变时，FF6,7的内容不相同，并且没有信号从门11,12输出。因此，即使由于抖动引起的短脉冲进入信号LS，也被消除。然后，通过将FF8的输出输入到计数器9来计数拨号脉冲数。另一方面，处理器1通过将特定地址发送到FF8和计数器9-1-9-4的内容，地址总线2。
